I put this on the British Forum and thought there might be those on this forum who might be interested as well.
The process is quite simple. Remove the mouthpiece from the neck of your sax and put the opening of the neck up to your ear like a stethoscope. Then finger low Bb and pop one of the lower stack keys open and closed. The F and the D keys work especially well. The resonance or "reverbration" of the sound you hear tells you a lot about the "integrity" of the air column inside the saxophone. The sound I like to hear after I have worked on a sax resembles that of a "tom-tom" with a nice "ring" to it.
Here are some links to some recordings I made using my SBA alto with roo pads. Notice there is no sticky pad noise present thanks to kangaroos who gave their all and a bit of Teflon powder.
Fingering low Bb and popping F key then D key on a leak free-saxophone
Popping F key with small leak then larger leak in D palm key
Popping F key with small leak then larger leak in side Bb key
